D
: Operation result
Description:
1. A logical AND operation is performed on the bit patterns of the contents of the two source
addresses (
S
2
and
S
1
). The result of the logical AND is stored in the destination address (
D
).
2. For 32-bit operation please refer to the DAND instruction.
Program Example:
When X0 = ON, the 16-bit sources D0 and D2 are analyzed and the result of the logical WAND
(Word AND) is stored in D4.
